"React Native for Web" brings the platform-agnostic Components and APIs of
[React Native][react-native-url] to the Web.
[React Native][react-native-url] components and APIs for the Web.
Browse the [interactive
documentation](https://necolas.github.io/react-native-web/storybook/) or [try
it out](https://glitch.com/edit/#!/react-native-web-playground) on Glitch.
Browser support: Chrome, Firefox, Safari >= 7, IE 10, Edge.
## Features

* Interoperability with ReactDOM components.
* Native-like touch handling.
* Built-in integration with web accessibility APIs.
* Built-in support for LTR and RTL layouts.
* Built-in expressive and reliable subset of CSS.
* Optimized, vendor-prefixed CSS with [good runtime performance](benchmarks/README.md).
* Server-side rendering of HTML and critical CSS.
* Browser support: Chrome, Firefox, Safari >= 7, IE 10, Edge.
## Overview
"React Native for Web" is a project to bring React Native's building blocks and
touch handling to the Web. [Read more](#why).
Browse the UI Explorer to see React Native [examples running on
Web](https://necolas.github.io/react-native-web/storybook/). Or try it out
online with [React Native for Web: Playground](http://codepen.io/necolas/pen/PZzwBR).
## Quick start
Install in your existing app using `yarn` or `npm`:
To install in your app:
```
yarn add react react-dom react-native-web
npm install --save react@15.3 react-native-web
```
Add the `react-native-web/babel` plugin to your Babel configuration. This will
alias `react-native` to `react-native-web` and exclude any modules not required
by the app.
Read the [Client and Server rendering](docs/guides/rendering.md) guide.
```json
{
"plugins": [
"react-native-web/babel"
],
"presets": [
"react-native"
]
}
```
(For React/ReactDOM 15.4 15.6 support, install `react-native-web@<0.1.0`)
See the [Getting Started](docs/guides/getting-started.md) guide for more details.
Alternatively, you can quickly setup a local project
using [create-react-app](https://github.com/facebookincubator/create-react-app)
(which supports `react-native-web` out-of-the-box once installed) and
[react-native-web-starter](https://github.com/grabcode/react-native-web-starter).

## Why?
There are many different teams at Twitter building web applications with React.
We want to share React components, libraries, and APIs between teams…much like
the OSS community tries to do. At our scale, this involves dealing with
multiple, inter-related problems including: a common way to handle style,
animation, touch, viewport adaptation, accessibility, themes, RTL layout, and
server-rendering.
This is hard to do with React DOM, as the components are essentially the same
low-level building blocks that the browser provides. However, React Native
avoids, solves, or can solve almost all these problems facing Web teams.
Central to this is React Native's JavaScript style API (not strictly
"CSS-in-JS") which avoids the key [problems with
CSS](https://speakerdeck.com/vjeux/react-css-in-js) by giving up some of the
complexity of CSS.

# Performance
To run these benchmarks from the root of the project:
```
yarn benchmark
open ./benchmarks/index.html
```
Append `?fastest` to the URL to include the fastest "other libraries", and
`?all` to include all the "other libraries".
## Notes
The components used in the render benchmarks are simple enough to be
implemented by multiple UI or style libraries. The implementations are not
equivalent in functionality. For example, React Native for Web's stylesheet is
unique in that it also converts React Native styles to DOM styles, has
deterministic resolution, and supports RTL layout.
`react-native-web/stylesheet` is a comparative baseline that implements a
simple `View` without much of React Native's functionality.
## Benchmark results
Typical render timings*: mean ± two standard deviations.
| Implementation | Deep tree (ms) | Wide tree (ms) | Tweets (ms) |
| :--- | ---: | ---: | ---: |
| `css-modules` | `88.83` `±18.63` | `198.79` `±22.98` | |
| `react-native-web/stylesheet@0.0.121` | `91.17` `±19.29` | `209.67` `±32.38` | |
| `react-native-web@0.0.121` | `124.21` `±16.84` | `264.55` `±38.75` | `16.90` `±7.30ms` |
Other libraries
| Implementation | Deep tree (ms) | Wide tree (ms) |
| :--- | ---: | ---: |
| `aphrodite@1.2.3` | `91.73` `±41.63` | `197.72` `±44.90` |
| `styletron@2.5.1` | `94.73` `±37.58` | `201.81` `±57.93` |
| `glamor@2.20.40` | `146.60` `±26.73` | `277.46` `±29.17` |
| `emotion@7.2.2` | `150.79` `±38.29` | `282.18` `±41.79` |
| `react-jss@7.1.0` | `201.83` `±34.65` | `428.61` `±47.8` |
| `reactxp@0.42.1` | `262.69` `±24.14` | `595.20` `±66.17` |
| `styled-components@2.1.2` | `280.59` `±31.77` | `599.00` `±62.99` |
| `styled-components/primitives@2.1.2` | `291.74` `±48.96` | `606.57` `±78.18` |
| `radium@0.19.4` | `563.94` `±69.91` | `1139.18` `±152.59` |
These results indicate that style render performance is not a significant
differentiating factor between `aphrodite`, `css-modules`, `react-native-web`,
and `styletron`.

# AppRegistry
`AppRegistry` is the control point for registering, running, prerendering, and
unmounting all apps. App root components should register themselves with
`AppRegistry.registerComponent`. Apps can be run by invoking
`AppRegistry.runApplication` (see the [client and server rendering
guide](../guides/rendering.md) for more details).
To "stop" an application when a view should be destroyed, call
`AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was passed
into `runApplication`. These should always be used as a pair.
## Methods
(web) static **getApplication**(appKey:string, appParameters: object)
Returns the given application element. Use this for server-side rendering.
Return object is of type `{ element: ReactElement; stylesheet: ReactElement }`.
It's recommended that you use `sheetsheet` to render the style sheet in an app
static **registerConfig**(config: Array<AppConfig>)
Registry multiple applications. `AppConfig` is of type `{ appKey: string;
component: ComponentProvider; run?: Function }`.
static **registerComponent**(appKey: string, getComponentFunc: ComponentProvider)
Register a component provider under the given `appKey`.
static **registerRunnable**(appKey: string, run: Function)
Register a custom render function for an application. The function will receive
the `appParameters` passed to `runApplication`.
static **getAppKeys**()
Returns all registered app keys.
static **runApplication**(appKey: string, appParameters?: object)
Runs the application that was registered under `appKey`. The `appParameters`
must include the `rootTag` into which the application is rendered, and
optionally any `initialProps`.
static **unmountApplicationComponentAtRootTag**(rootTag: HTMLElement)
To "stop" an application when a view should be destroyed, call
`AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was passed
into `runApplication`
## Example
```js
AppRegistry.registerComponent('MyApp', () => AppComponent)
AppRegistry.runApplication('MyApp', {
initialProps: {},
rootTag: document.getElementById('react-root')
})
```

## AppState
`AppState` can tell you if the app is in the foreground or background, and
notify you when the state changes.
States
* `active` - The app is running in the foreground
* `background` - The app is running in the background (i.e., the user has not focused the app's tab).
## Properties
static **currentState**
Returns the current state of the app: `active` or `background`.
## Methods
static **addEventListener**(type: string, handler: Function)
Add a handler to `AppState` changes by listening to the `change` event type and
providing the `handler`. The handler is called with the app state value.
static **removeEventListener**(type: string, handler: Function)
Remove a handler by passing the change event `type` and the `handler`.
## Examples
To see the current state, you can check `AppState.currentState`, which will be
kept up-to-date. This example will only ever appear to say "Current state is:
active" because the app is only visible to the user when in the `active` state,
and the null state will happen only momentarily.
```js
class Example extends React.Component {
constructor(props) {
super(props)
this.state = { currentAppState: AppState.currentState }
}
componentDidMount() {
AppState.addEventListener('change', this._handleAppStateChange);
}
componentWillUnmount() {
AppState.removeEventListener('change', this._handleAppStateChange);
}
_handleAppStateChange = (currentAppState) => {
this.setState({ currentAppState });
}
render() {
return (
<Text>Current state is: {this.state.currentAppState}</Text>
)
}
}

# AsyncStorage
`AsyncStorage` is a simple, asynchronous, persistent, key-value storage system
that is global to the domain. It's a facade over, and should be used instead of
`window.localStorage` to provide an asynchronous API and multi functions. Each
method returns a `Promise` object.
It is recommended that you use an abstraction on top of `AsyncStorage` instead
of `AsyncStorage` directly for anything more than light usage since it operates
globally.
The batched functions are useful for executing a lot of operations at once,
allowing for optimizations to provide the convenience of a single promise after
all operations are complete.
## Methods
static **clear**()
Erases all AsyncStorage. You probably don't want to call this - use
`removeItem` or `multiRemove` to clear only your own keys instead. Returns a
Promise object.
static **getAllKeys**()
Gets all known keys. Returns a Promise object.
static **getItem**(key: string)
Fetches the value of the given key. Returns a Promise object.
static **mergeItem**(key: string, value: string)
Merges existing value with input value, assuming they are stringified JSON.
Returns a Promise object.
static **multiGet**(keys: Array<string>)
`multiGet` results in an array of key-value pair arrays that matches the input
format of `multiSet`. Returns a Promise object.
```js
multiGet(['k1', 'k2']) -> [['k1', 'val1'], ['k2', 'val2']]
```
static **multiMerge**(keyValuePairs: Array<Array<string>>)
multiMerge takes an array of key-value array pairs that match the output of
`multiGet`. It merges existing values with input values, assuming they are
stringified JSON. Returns a Promise object.
static **multiRemove**(keys: Array<string>)
Delete all the keys in the keys array. Returns a Promise object.
static **multiSet**(keyValuePairs: Array<Array<string>>)
`multiSet` takes an array of key-value array pairs that match the output of
`multiGet`. Returns a Promise object.
```js
multiSet([['k1', 'val1'], ['k2', 'val2']]);
```
static **removeItem**(key: string)
Removes the value of the given key. Returns a Promise object.
static **setItem**(key: string, value: string)
Sets the value of the given key. Returns a Promise object.

# Dimensions
Note: dimensions may change (e.g due to device rotation) so any rendering logic
or styles that depend on these constants should try to call this function on
every render, rather than caching the value.

Allow the application to display in RTL mode.
static **forceRTL**(forceRTL: bool)
Force the application to display in RTL mode.
static **setPreferredLanguageRTL**(isRTL: bool)
Set the application's preferred writing direction to RTL. You will need to
determine the user's preferred locale server-side (from HTTP headers) and
decide whether it's an RTL language.

# NativeMethods
React Native for Web provides several methods to directly access the underlying
DOM node. This can be useful in cases when you want to focus a view or measure
its on-screen dimensions, for example.
The methods described are available on most of the default components provided
by React Native for Web. Note, however, that they are *not* available on the
composite components that you define in your own app. For more information, see
[Direct Manipulation](../guides/direct-manipulation.md).
## Methods
**blur**()
Removes focus from an input or view. This is the opposite of `focus()`.
**focus**()
Requests focus for the given input or view. The exact behavior triggered will
depend the type of view.
**measure**(callback: (x, y, width, height, pageX, pageY) => void)
For a given view, `measure` determines the offset relative to the parent view,
width, height, and the offset relative to the viewport. Returns the values via
an async callback.
Note that these measurements are not available until after the rendering has
been completed.
**measureLayout**(relativeToNativeNode: DOMNode, onSuccess: (x, y, width, height) => void)
Like `measure`, but measures the view relative to another view, specified as
`relativeToNativeNode`. This means that the returned `x`, `y` are relative to
the origin `x`, `y` of the ancestor view.
**setNativeProps**(nativeProps: Object)
This function sends props straight to the underlying DOM node. See the [direct
manipulation](../guides/direct-manipulation.md) guide for cases where
`setNativeProps` should be used.

# NetInfo
`NetInfo` asynchronously determines the online/offline status of the
application.
Connection types:
* `bluetooth` - The user agent is using a Bluetooth connection.
* `cellular` - The user agent is using a cellular connection (e.g., EDGE, HSPA, LTE, etc.).
* `ethernet` - The user agent is using an Ethernet connection.
* `mixed` - The user agent is using multiple connection types.
* `none` - The user agent will not contact the network (offline).
* `other` - The user agent is using a connection type that is not one of enumerated connection types.
* `unknown` - The user agent has established a network connection, but is unable to determine what is the underlying connection technology.
* `wifi` - The user agent is using a Wi-Fi connection.
* `wimax` - The user agent is using a WiMAX connection.
## Methods
Note that support for retrieving the connection type depends upon browswer
support (and is limited to mobile browsers). It will default to `unknown` when
support is missing.
static **addEventListener**(eventName: ChangeEventName, handler: Function)
static **fetch**(): Promise
static **removeEventListener**(eventName: ChangeEventName, handler: Function)
## Properties
**isConnected**: bool = true
Available on all user agents. Asynchronously fetch a boolean to determine
internet connectivity.
**isConnected.addEventListener**(eventName: ChangeEventName, handler: Function)
**isConnected.fetch**(): Promise
**isConnected.removeEventListener**(eventName: ChangeEventName, handler: Function)
## Examples
Fetching the connection type:
```js
NetInfo.fetch().then((connectionType) => {
console.log('Connection type:', connectionType);
});
```
Subscribing to changes in the connection type:
```js
const handleConnectivityTypeChange = (connectionType) => {
console.log('Current connection type:', connectionType);
}
NetInfo.addEventListener('change', handleConnectivityTypeChange);
```
Fetching the connection status:
```js
NetInfo.isConnected.fetch().then((isConnected) => {
console.log('Connection status:', (isConnected ? 'online' : 'offline'));
});
```
Subscribing to changes in the connection status:
```js
const handleConnectivityStatusChange = (isConnected) => {

# PixelRatio
`PixelRatio` gives access to the device pixel density.
## Methods
static **get**()
Returns the device pixel density. Some examples:
* PixelRatio.get() === 1
* mdpi Android devices (160 dpi)
* PixelRatio.get() === 1.5
* hdpi Android devices (240 dpi)
* PixelRatio.get() === 2
* iPhone 4, 4S
* iPhone 5, 5c, 5s
* iPhone 6
* xhdpi Android devices (320 dpi)
* PixelRatio.get() === 3
* iPhone 6 plus
* xxhdpi Android devices (480 dpi)
* PixelRatio.get() === 3.5
* Nexus 6
static **getPixelSizeForLayoutSize**(layoutSize: number)
Converts a layout size (dp) to pixel size (px). Guaranteed to return an integer
number.
static **roundToNearestPixel**(layoutSize: number)
Rounds a layout size (dp) to the nearest layout size that corresponds to an
integer number of pixels. For example, on a device with a PixelRatio of 3,
`PixelRatio.roundToNearestPixel(8.4)` = `8.33`, which corresponds to exactly
`(8.33 * 3)` = `25` pixels.
## Examples
Fetching a correctly sized image. You should get a higher resolution image if
you are on a high pixel density device. A good rule of thumb is to multiply the
size of the image you display by the pixel ratio.
```js
const image = getImage({
width: PixelRatio.getPixelSizeForLayoutSize(200),
height: PixelRatio.getPixelSizeForLayoutSize(100),
});
<Image source={image} style={{ width: 200, height: 100 }} />
```

# Platform
Detect what is the platform in which the app is running. This piece of
functionality can be useful when only small parts of a component are platform
specific.
## Properties
**OS**: string
`Platform.OS` will be `web` when running in a Web browser.
```js
import { Platform } from 'react-native';
const styles = StyleSheet.create({
height: (Platform.OS === 'web') ? 200 : 100,
});
```
## Methods
**select**(object): any
`Platform.select` takes an object containing `Platform.OS` as keys and returns
the value for the platform you are currently running on.
```js
import { Platform } from 'react-native';
const containerStyles = {
flex: 1,
...Platform.select({
android: {
backgroundColor: 'blue'
},
ios: {
backgroundColor: 'red'
},
web: {
backgroundColor: 'green'
}
})
});

# StyleSheet
The `StyleSheet` abstraction converts predefined styles to (vendor-prefixed)
CSS without requiring a compile-time step. Some styles cannot be resolved
outside of the render loop and are applied as inline styles. Read more about
[how to style your application](../guides/style.md).
## Methods
**create**(obj: {[key: string]: any})
Each key of the object passed to `create` must define a style object.
**flatten**: function
Flattens an array of styles into a single style object.
**render**: function
Returns a React `<style>` element for use in server-side rendering.
## Properties
**absoluteFill**: number
A very common pattern is to create overlays with position absolute and zero positioning,
so `absoluteFill` can be used for convenience and to reduce duplication of these repeated
styles.
```js
<View style={StyleSheet.absoluteFill} />
```
**absoluteFillObject**: object
Sometimes you may want `absoluteFill` but with a couple tweaks - `absoluteFillObject` can be
used to create a customized entry in a `StyleSheet`, e.g.:
```js
const styles = StyleSheet.create({
wrapper: {
...StyleSheet.absoluteFillObject,
backgroundColor: 'transparent',
top: 10
}
})
```
**hairlineWidth**: number
## Example
```js
<View style={styles.container}>
<Text
children={'Title text'}
style={[
styles.title,
this.props.isActive && styles.activeTitle
]}
/>
</View>
const styles = StyleSheet.create({
container: {
borderRadius: 4,
borderWidth: 0.5,
borderColor: '#d6d7da',
},
title: {
fontSize: 19,
fontWeight: 'bold',
},
activeTitle: {
color: 'red',
}

# Vibration
Vibration is described as a pattern of on-off pulses, which may be of varying
lengths. The pattern may consist of either a single integer, describing the
number of milliseconds to vibrate, or an array of integers describing a pattern
of vibrations and pauses. Vibration is controlled with a single method:
`Vibration.vibrate()`.
The vibration is asynchronous so this method will return immediately. There
will be no effect on devices that do not support vibration.
## Methods
static **cancel**()
Stop the vibration.
static **vibrate**(pattern)
Start the vibration pattern.
## Examples
Vibrate once for 200ms:
```js
Vibration.vibrate(200);
Vibration.vibrate([200]);
```
Vibrate for 200ms, pause for 100ms, vibrate for 200ms:
```js
Vibration.vibrate([200, 100, 200]);

# ScrollView
A scrollable `View` that provides itegration with the touch-locking "responder"
system. `ScrollView`'s must have a bounded height: either set the height of the
view directly (discouraged) or make sure all parent views have bounded height
(e.g., transfer `{ flex: 1}` down the view stack).
## Props
[...View props](./View.md)
**contentContainerStyle**: style
These styles will be applied to the scroll view content container which wraps
all of the child views.
**horizontal**: bool = false
When true, the scroll view's children are arranged horizontally in a row
instead of vertically in a column.
**keyboardDismissMode**: oneOf('none', 'on-drag') = 'none'
Determines whether the keyboard gets dismissed in response to a scroll drag.
* `none` (the default), drags do not dismiss the keyboard.
* `on-drag`, the keyboard is dismissed when a drag begins.
* `interactive` (not supported on web; same as `none`)
**onContentSizeChange**: function
Called when scrollable content view of the `ScrollView` changes. It's
implemented using the `onLayout` handler attached to the content container
which this `ScrollView` renders.
**onScroll**: function
Fires at most once per frame during scrolling. The frequency of the events can
be contolled using the `scrollEventThrottle` prop.
Invoked on scroll with the following event:
```js
{
nativeEvent: {
contentOffset: { x, y },
contentSize: { height, width },
layoutMeasurement: { height, width }
}
}
```
**refreshControl**: element
TODO
A [RefreshControl](../RefreshControl) component, used to provide
pull-to-refresh functionality for the `ScrollView`.
**scrollEnabled**: bool = true
When false, the content does not scroll.
**scrollEventThrottle**: number = 0
This controls how often the scroll event will be fired while scrolling (as a
time interval in ms). A lower number yields better accuracy for code that is
tracking the scroll position, but can lead to scroll performance problems. The
default value is `0`, which means the scroll event will be sent only once each
time the view is scrolled.
## Instance methods
**getInnerViewNode()**: any
Returns a reference to the underlying content container DOM node within the `ScrollView`.
**getScrollableNode()**: any
Returns a reference to the underlying scrollable DOM node.
**getScrollResponder()**: Component
Returns a reference to the underlying scroll responder, which supports
operations like `scrollTo`. All `ScrollView`-like components should implement
this method so that they can be composed while providing access to the
underlying scroll responder's methods.
**scrollTo(options: { x: number = 0; y: number = 0; animated: boolean = true })**
Scrolls to a given `x`, `y` offset (animation is not currently supported).
## Examples
```js
import React, { Component } from 'react'
import { ScrollView, StyleSheet } from 'react-native'
import Item from './Item'
export default class ScrollViewExample extends Component {
constructor(props, context) {
super(props, context)

# Text
`Text` is component for displaying text. It supports style, basic touch
handling, and inherits typographic styles from ancestor elements.
The `Text` is unique relative to layout: child elements use text layout
(`inline`) rather than flexbox layout. This means that elements inside of a
`Text` are not rectangles, as they wrap when reaching the edge of their
container.
Unsupported React Native props:
`allowFontScaling` (ios),
`suppressHighlighting` (ios)
## Props
NOTE: `Text` will transfer all other props to the rendered HTML element.
(web) **accessibilityLabel**: string
Defines the text available to assistive technologies upon interaction with the
element. (This is implemented using `aria-label`.)
(web) **accessibilityRole**: oneOf(roles)
Allows assistive technologies to present and support interaction with the view
in a manner that is consistent with user expectations for similar views of that
type. For example, marking a touchable view with an `accessibilityRole` of
`button`. (This is implemented using [ARIA roles](http://www.w3.org/TR/wai-aria/roles#role_definitions)).
Note: Avoid changing `accessibilityRole` values over time or after user
actions. Generally, accessibility APIs do not provide a means of notifying
assistive technologies of a `role` value change.
**accessible**: bool = true
When `false`, the text is hidden from assistive technologies. (This is
implemented using `aria-hidden`.)
**children**: any
Child content.
**numberOfLines**: number
Truncates the text with an ellipsis after this many lines. Currently only supports `1`.
**onLayout**: function
Invoked on mount and layout changes with `{ nativeEvent: { layout: { x, y, width,
height } } }`, where `x` and `y` are the offsets from the parent node.
**onPress**: function
This function is called on press.
**selectable**: bool = true
Lets the user select the text.
**style**: style
+ ...[View#style](View.md)
+ `color`
+ `fontFamily`
+ `fontSize`
+ `fontStyle`
+ `fontWeight`
+ `letterSpacing`
+ `lineHeight`
+ `textAlign`

+ `textShadowColor`
+ `textShadowOffset`
+ `textShadowRadius`

+ `wordWrap`
+ `writingDirection`
‡ This property can be suffixed with `$noI18n` to prevent automatic
bidi-flipping in RTL mode. This is only supported if `Platform.OS === 'web'`.
**testID**: string
Used to locate this view in end-to-end tests.

`onEndEditing`,
`clearButtonMode` (ios),
`enablesReturnKeyAutomatically` (ios),
`placeholderTextColor`,
`returnKeyType` (ios),
`selectionState` (ios),
`underlineColorAndroid` (android)
## Props
[...View props](./View.md)
**autoCapitalize**: oneOf('characters', 'none', 'sentences', 'words') = 'sentences'
Automatically capitalize certain characters (only available in Chrome and iOS Safari).
* `characters`: Automatically capitalize all characters.
* `none`: Completely disables automatic capitalization
* `sentences`: Automatically capitalize the first letter of sentences.
* `words`: Automatically capitalize the first letter of words.
(web) **autoComplete**: string
Indicates whether the value of the control can be automatically completed by
the browser. [Accepted values](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input).
**autoCorrect**: bool = true
Automatically correct spelling mistakes (only available in iOS Safari).
**autoFocus**: bool = false
If `true`, focuses the input on `componentDidMount`. Only the first form element
in a document with `autofocus` is focused.
**blurOnSubmit**: bool
If `true`, the text field will blur when submitted. The default value is `true`
for single-line fields and `false` for multiline fields. Note, for multiline
fields setting `blurOnSubmit` to `true` means that pressing return will blur
the field and trigger the `onSubmitEditing` event instead of inserting a
newline into the field.
**clearTextOnFocus**: bool = false
If `true`, clears the text field automatically when focused.
**defaultValue**: string
Provides an initial value that will change when the user starts typing. Useful
for simple use-cases where you don't want to deal with listening to events and
updating the `value` prop to keep the controlled state in sync.
**editable**: bool = true
If `false`, text is not editable (i.e., read-only).
**keyboardType**: oneOf('default', 'email-address', 'numeric', 'phone-pad', 'search', 'url', 'web-search') = 'default'
Determines which keyboard to open. (NOTE: Safari iOS requires an ancestral
`<form action>` element to display the `search` keyboard).
(Not available when `multiline` is `true`.)
**maxLength**: number
Limits the maximum number of characters that can be entered.
(web) **maxNumberOfLines**: number = numberOfLines
Limits the maximum number of lines for a multiline `TextInput`.
(Requires `multiline` to be `true`.)
**multiline**: bool = false
If true, the text input can be multiple lines.
**numberOfLines**: number = 2
Sets the initial number of lines for a multiline `TextInput`.
(Requires `multiline` to be `true`.)
**onBlur**: function
Callback that is called when the text input is blurred.
**onChange**: function
Callback that is called when the text input's text changes.
**onChangeText**: function
Callback that is called when the text input's text changes. The text is passed
as an argument to the callback handler.
**onFocus**: function
Callback that is called when the text input is focused.
**onKeyPress**: function
Callback that is called when a key is pressed. Pressed key value is passed as
an argument to the callback handler. Fires before `onChange` callbacks.
**onSelectionChange**: function
Callback that is called when the text input's selection changes. This will be called with
`{ nativeEvent: { selection: { start, end } } }`.
**onSubmitEditing**: function
Callback that is called when the keyboard's submit button is pressed.
**placeholder**: string
The string that will be rendered in an empty `TextInput` before text has been
entered.
**secureTextEntry**: bool = false
If true, the text input obscures the text entered so that sensitive text like
passwords stay secure.
(Not available when `multiline` is `true`.)
**selection**: { start: number, end: ?number }
The start and end of the text input's selection. Set start and end to the same value to position the cursor.
**selectTextOnFocus**: bool = false
If `true`, all text will automatically be selected on focus.
**style**: style
+ ...[Text#style](./Text.md)
+ `outline`
**testID**: string
Used to locate this view in end-to-end tests.
**value**: string
The value to show for the text input. `TextInput` is a controlled component,
which means the native `value` will be forced to match this prop if provided.
Read about how [React form
components](https://facebook.github.io/react/docs/forms.html) work. To prevent
user edits to the value set `editable={false}`.
## Instance methods
**blur()**
Blur the underlying DOM input.
**clear()**
Clear the text from the underlying DOM input.
**focus()**
Focus the underlying DOM input.
**isFocused()**
Returns `true` if the input is currently focused; `false` otherwise.

# TouchableWithoutFeedback
Do not use unless you have a very good reason. All the elements that respond to
press should have a visual feedback when touched. This is one of the primary
reason a "web" app doesn't feel "native".
**NOTE: `TouchableWithoutFeedback` supports only one child**. If you wish to have
several child components, wrap them in a View.
## Props

**accessibilityLabel**: string
Overrides the text that's read by the screen reader when the user interacts
with the element.
(web) **accessibilityRole**: oneOf(roles) = 'button'
Allows assistive technologies to present and support interaction with the view
**accessible**: bool = true
When `false`, the view is hidden from screenreaders.
**children**: View
**delayLongPress**: number
Delay in ms, from `onPressIn`, before `onLongPress` is called.
**delayPressIn**: number
Delay in ms, from the start of the touch, before `onPressIn` is called.
**delayPressOut**: number
Delay in ms, from the release of the touch, before `onPressOut` is called.
**disabled**: bool
If true, disable all interactions for this component.
**hitSlop**: `{top: number, left: number, bottom: number, right: number}`
This defines how far your touch can start away from the button. This is added
to `pressRetentionOffset` when moving off of the button. **NOTE**: The touch
area never extends past the parent view bounds and the z-index of sibling views
always takes precedence if a touch hits two overlapping views.
**onLayout**: function
Invoked on mount and layout changes with `{ nativeEvent: { layout: { x, y, width,
height } } }`, where `x` and `y` are the offsets from the parent node.
**onLongPress**: function
**onPress**: function
Called when the touch is released, but not if cancelled (e.g. by a scroll that steals the responder lock).
**onPressIn**: function
**onPressOut**: function
**pressRetentionOffset**: `{top: number, left: number, bottom: number, right: number}`
When the scroll view is disabled, this defines how far your touch may move off
of the button, before deactivating the button. Once deactivated, try moving it
back and you'll see that the button is once again reactivated! Move it back and
forth several times while the scroll view is disabled. Ensure you pass in a
constant to reduce memory allocations.

# View
`View` is the fundamental UI building block. It is a component that supports
style, layout with flexbox, and accessibility controls. It can be nested
inside another `View` and has 0-to-many children of any type.
Also, refer to React Native's documentation about the [Gesture Responder
System](http://facebook.github.io/react-native/releases/0.22/docs/gesture-responder-system.html).
Unsupported React Native props:
`onAccessibilityTap`,
`hitSlop`,
`onMagicTap`
## Props
NOTE: `View` will transfer all other props to the rendered HTML element.
**accessibilityLabel**: string
Defines the text available to assistive technologies upon interaction with the
element. (This is implemented using `aria-label`.)
**accessibilityLiveRegion**: oneOf('assertive', 'off', 'polite') = 'off'
Indicates to assistive technologies whether to notify the user when the view
changes. The values of this attribute are expressed in degrees of importance.
When regions are specified as `polite` (recommended), updates take low
priority. When regions are specified as `assertive`, assistive technologies
will interrupt and immediately notify the user. (This is implemented using
[`aria-live`](http://www.w3.org/TR/wai-aria/states_and_properties#aria-live).)
(web) **accessibilityRole**: oneOf(roles)
Allows assistive technologies to present and support interaction with the view
in a manner that is consistent with user expectations for similar views of that
type. For example, marking a touchable view with an `accessibilityRole` of
`button`. (This is implemented using [ARIA roles](http://www.w3.org/TR/wai-aria/roles#role_definitions)).
Note: Avoid changing `accessibilityRole` values over time or after user
actions. Generally, accessibility APIs do not provide a means of notifying
assistive technologies of a `role` value change.
**accessible**: bool = true
When `false`, the view is hidden from assistive technologies. (This is
implemented using `aria-hidden`.)
**onLayout**: function
Invoked on mount and layout changes with `{ nativeEvent: { layout: { x, y, width,
height } } }`, where `x` and `y` are the offsets from the parent node.
**onMoveShouldSetResponder**: function
**onMoveShouldSetResponderCapture**: function
**onResponderGrant**: function
For most touch interactions, you'll simply want to wrap your component in
`TouchableHighlight` or `TouchableOpacity`.
**onResponderMove**: function
**onResponderReject**: function
**onResponderRelease**: function
**onResponderTerminate**: function
**onResponderTerminationRequest**: function
**onStartShouldSetResponder**: function
**onStartShouldSetResponderCapture**: function
**pointerEvents**: oneOf('auto', 'box-only', 'box-none', 'none') = 'auto'
Configure the `pointerEvents` of the view. The enhanced `pointerEvents` modes
provided are not part of the CSS spec, therefore, `pointerEvents` is excluded
from `style`.
`box-none` is the equivalent of:
```css
.box-none { pointer-events: none }
.box-none * { pointer-events: auto }
```
`box-only` is the equivalent of:
```css
.box-only { pointer-events: auto }
.box-only * { pointer-events: none }
```

‡ This property can be suffixed with `$noI18n` to prevent automatic
bidi-flipping in RTL mode. This is only supported if `Platform.OS === 'web'`.
Default:
```js
{
alignItems: 'stretch',
borderWidth: 0,
borderStyle: 'solid',
boxSizing: 'border-box',
display: 'flex',
flexBasis: 'auto',
flexDirection: 'column',
flexShrink: 0,
margin: 0,
padding: 0,
position: 'relative'
};
```
(See [facebook/css-layout](https://github.com/facebook/css-layout)).
**testID**: string
Used to locate this view in end-to-end tests.
## Examples
```js
import React, { Component, PropTypes } from 'react'
import { StyleSheet, View } from 'react-native'
export default class ViewExample extends Component {
render() {
return (
<View style={styles.row}>
{
['1', '2', '3', '4', '5'].map((value, i) => {
return <View children={value} key={i} style={styles.cell} />
})
}
</View>
);
}
}
const styles = StyleSheet.create({
row: {
flexDirection: 'row'
},
cell: {
flexGrow: 1
}
})
```
